From 0cbb65479147ecdaa664e88cc2a5a925f3de502f Mon Sep 17 00:00:00 2001 From: nsz Date: Mon, 19 Mar 2012 23:41:19 +0100 Subject: code cleanup of named constants zero, one, two, half are replaced by const literals The policy was to use the f suffix for float consts (1.0f), but don't use suffix for long double consts (these consts can be exactly represented as double). --- src/math/__cos.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'src/math/__cos.c') diff --git a/src/math/__cos.c b/src/math/__cos.c index ba439857..8699c1d5 100644 --- a/src/math/__cos.c +++ b/src/math/__cos.c @@ -51,7 +51,6 @@ #include "libm.h" static const double -one = 1.00000000000000000000e+00, /* 0x3FF00000, 0x00000000 */ C1 = 4.16666666666666019037e-02, /* 0x3FA55555, 0x5555554C */ C2 = -1.38888888888741095749e-03, /* 0xBF56C16C, 0x16C15177 */ C3 = 2.48015872894767294178e-05, /* 0x3EFA01A0, 0x19CB1590 */ @@ -67,6 +66,6 @@ double __cos(double x, double y) w = z*z; r = z*(C1+z*(C2+z*C3)) + w*w*(C4+z*(C5+z*C6)); hz = 0.5*z; - w = one-hz; - return w + (((one-w)-hz) + (z*r-x*y)); + w = 1.0-hz; + return w + (((1.0-w)-hz) + (z*r-x*y)); } -- cgit v1.2.1
